Brad, Richard, Thanks for your comments. The comparison doc gives is based on the systems that we looked at, around the beginning of 2014. A better place for an up-to-date comparison or list of geocode systems would be a wikipedia page.
I don't think we need a list of reference locations. If it's a list with locations, then it has to be distributed in various languages, it has to be free to use, and I don't want to have to ship data files around because that's just awful. I think that people will end up picking stuff that works and that it won't be that hard. With OLC codes you don't have to be very close to the reference (within 50km is enough), so if you live in a slum area such as Kibera or Dharavi, you can use the nearest city as your reference (Nairobi or Mumbai) and it will work.
